The Honda M55-TLAN1816 Needle Bearing is a genuine OEM component designed for WDP20 and WDP30 diaphragm water pumps. Sourced directly from Honda, this bearing carries the same specifications as the part installed at the factory. Confirm your pump's serial number against the fitment table before ordering, as Honda updates part numbers at production breaks.
Key Features
- Genuine OEM Fit — supplied by Honda to the same specification as the original, ensuring the bearing seats correctly within the diaphragm pump's drive assembly.
- Diaphragm Pump Application — listed for the WDP20 and WDP30 diaphragm water pumps; verify your serial number against the compatibility table to confirm the correct match for your unit.
- Direct Replacement — replaces the worn or failed needle bearing with an exact Honda part, restoring smooth, low-friction operation to the pump's reciprocating drive mechanism.
In a WDP-series diaphragm water pump, the needle bearing supports the rotating crank or drive shaft that converts engine power into the reciprocating motion of the diaphragm. A needle bearing's compact, high-load design allows it to handle the continuous radial loads generated by this back-and-forth motion in a tight space. When the bearing wears or fails, increased friction and play develop in the drive assembly, leading to accelerated wear on surrounding components and a loss of pumping efficiency.
